Abstract

A resin composite in which a fiber-reinforced resin material comprising fibers and a resin, and a resin expanded body are integrally laminated, wherein the resin expanded body has a hole opened at the interface with the fiber-reinforced resin material and resin of the fiber-reinforced resin material is caused to flow into the hole.

First claim

What is claimed is:

1 . A resin composite in which a fiber-reinforced resin material comprising fibers and a resin, and a resin expanded body are integrally laminated, wherein said resin expanded body has a hole opened at an interface between said resin expanded body and said fiber-reinforced resin material, and said fiber-reinforced resin material and said resin expanded body are integrally laminated by making a resin of said fiber-reinforced resin material to flow into said hole.

2 . The resin composite according to claim 1 , wherein said resin expanded body is formed by thermally fusing a plurality a resin expanded particles to each other, said resin expanded particles forming an interface between said resin expanded body and said fiber-reinforced resin material have said hole, and said resin is caused to flow into an inner area of said resin expanded particles.

3 . The resin composite according to claim 1 , wherein said resin expanded body is formed by a plurality of resin expanded particles being integrated by direct thermal fusion, a void section is formed between said resin expanded particles, and said hole is formed in a surface by opening said void section.

4 . The resin composite according to claim 3 , wherein said void section penetrates from a first surface having said opening to a second surface, which is a surface opposite to said first surface, and said void section is also open in said second surface, and said fiber-reinforced resin material is laminated on both said first surface and said second surface, and said fiber-reinforced resin material is continuously integrated by a resin that has been caused to flow into said void section.

5 . The resin composite according to claim 3 , wherein a proportion of said void section occupying said resin expanded body is 0.1 to 50% by volume.

6 . A method for producing a resin composite, said method producing a resin composite in which a fiber-reinforced resin material comprising fibers and a resin, and a resin expanded body are integrally laminated, wherein said fiber-reinforced resin material is laminated on said resin expanded body, which has a hole opened on the surface, and the lamination is carried out by arranging the opening at an interface between said resin expanded body and said fiber-reinforced resin material, and said fiber-reinforced resin material and said resin expanded body are integrally laminated by causing said resin of said fiber-reinforced resin material to flow into said hole of said resin expanded body.
